T0 all Iwhom it may concern.' A

Be it known that I, WILLIAM IVALTER HARTMAN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have inventecI a new and useful Sugar-Washing and Tater-Measuring Device, of which the following is a specification.

In washing sugar centrifugals it is desirable that the water be distributed scientifically over the entire sugar wall, and this problem is complicated somewhat by the fact that the wall usually diminishes gradually in thickness from the bottom toward the top 0f the basket. y

Among other objects, it is an object of this invention to improve and simplify all centrifugal sugar-washing machines in general, but in particular to improve that class of scientific washers in which a spray of washwater is alternately swept along the height of the centrifugal basket, traveling slower below where the sugar wall is thick, and more rapidly above where the sugar wall is thinner and varying gradually in between in proportion to the thickness of the sugar wall at the successivelevels.

In addition, and with reference to all types of centrifugal sugarl washers, this invention is broadly new, basic and pioneer in that the apparatus is so constructed that it is driven directly from the power which rotates the centrifugal basket and through this agency several important advantages are gained, as will appear in subsequent parts of this specification.

Further objects, advantages and features of the invention may appear from the accompanying drawings, the subjoined detailed description and the appended claims.

Reference is hereby made to my copend# ing application, Serial No. 453,956, filed March 21st, 1921, and permission is hereby reserved t0 claim in that application sep-` arately patentable matter shown but -not claimed in this application. ,l

In fact in drawing the claims herein I have confined this application to the aforesaid separate invention of driving the sprayer parts from the centrifugal shaft, and each of the claims in this application will be found'to depend for its novelty upon this basic feature of driving from the centrifugal shaft, the same being variously Figure 1 is an elevation of sugar washing apparatus, constructed in accordance with this inventionV and applied, in connection with a sugar centrifugal, which isfshown mainly in vertical mid-section on line m1 Fig. 2.

Fig. 12 is a sectional elevation on line zal? '.Figs. 6 and 8; vand drawn to the same scale as Figs. 10 and 11. u Fig. 13 is` a section .on the line w13 of Fig. 3. i i f In detail the centrifugal sugar separator 1 is provided with a receptacle having a cylindrical wall 2;l and on the upper end of this wall 2 there is secured ai'angev top piece 3, which top piece has onk the flange 4 thereof the disk 5. 4

The disk 5 has a central opening 6 that is larger than the top opening 7 in the cen-r trifugal basket 8; and as seen in Fig.l1- the drawn to the same top of thel basket 8 is provided with the beveled plate 9 which plate has the opening 7 therethrough; and the purpose of vthis plate is' to preventV the massecuite from climbing over the top of the basket 8 when this material is subjected to centrifugal force.

The basket 8 is provided with the usual opening 10 in the bottom thereof which opening is normally closed by the cover 11 which cover is slidably mounted on the vertical shaft 12.

The basket 8 is secured in the usual way to the bottom endvof the shaft 12 thereby allowing the basket and shaft Ito gyrate about an upper support in a manner well known to those acquainted in the art.

The rapid rotation or spinning of the basket 8 causes the massecuite to climb the perforated wall 13 of the basket 8, and through the perforations of the wall 13 the molasses escapes from the massecuite and leaves in the basket the sugar crystals which sugar is compactly formed into a cylindri- ,calvwall 14. All of the foregoing mechanism and its operation is old and well understood and is given to make clear the purpose of this invention.

A general purpose of this invention is to supply a means for cleansing the wall of sugar; for, as is well known, centrifugal force alone is not suiiicient to drive all of the molasses from the. sugar wall; conse quently it Vis necessary to apply a small water spray to the inner side of thevcylindrical wall of sugar vto dissolve the molasses and reduce the adhesiveness thereof so that the centrifugal force imparted to the basket will remove this residue of syrup, but this washing of the sugar wall requires great skill in order to cleanse the sugar crystals without dissolving them.

The application of the washing water to the sugar wall 14 is applied in the following manner.

14 spray nozzle 15 has integral therewith one end of the cylinder 16 and this cylinder is loosely mounted in the casing 17 which casing is also cylindrical in form.

The other end of the cylinder 16 is threaded, and secured thereto is the cap nut 18, which nut when tightened contacts with one end of the casing 17 and also draws the shoulder 19 of the nozzle `15 tightly against the other end of the casing 17 and the tight contact of the nut 18 and shoulder 19 with the casing 17 holds the nozzle 15 in a fixed position relative to the casing. To adjust-.the nozzle to, another position the nut 18 isloosened-sov that the cylinder 16 `can be turned in the casing 17 and when the adjustment is accomplished the tension of the parts can again be established for thepurpose specified.

A pipe 20 has one end thereof attached to the casing 17 and openings in the casing 17 and cylinder 16 register with the opening through the pipe 2O so that water passing through said pipe to the nozzle 15 will discharge therefrom through the small openings 21.

Near the other end of the pipe 20, and on the underside thereof there is secured the bearing 22 that is secured by the key 23 to one end of the rocker shaft 24, see Figs. -1 and 3; and by means of the rocker shaft 24 the nozzle 15 is oscillated to move the spray of washing water alternately from the top to the bottom of the sugar wall 14 as shown by the full and dotted lines in Fig. 1.

As this spray is moved alternately from its highest to its lowest position the sugar wall 14 is revolved so that in reality the contact of the spray ivith the wall is in a helical course in one direction as the spray moves downward and a reverse helix as the spray moves upward; and also the movement of the spray upward and downward is timedL so it will contact with the entire inner surface of the sugar wall 14.

The shaft 24 is mounted in a bearing 25 that is integral with the end wall of a boX 26, which box is secured to the disk 5 by bolts 26 as seen in Figs. 1, 2 and 3. other end of the shaft 24 has thereon the rocker arm 27, which arm has thereon the roller 2S and this roller is'held in contact with the vperiphery of the cam 29 by a spring 30 and one end of this spring 1s secured to the wall of the boX 26 and the other end to the arm 27.

The cam 29 is keyed to the hub 31 of the worm gear 32 and additionally secured to said gear by the screw 33, see Fig. S; so that when the worm gear 32 is rotated it will turn the cam to depress the rocker arm 27 which movement of the arm 27 oscillates the pipe 2O and the spray nozzle 15.

The cam 29 is carefully constructed so that it operates the roller 28 and consequently the rock arm 27 and rock shaft 24 and consequently the nozzle 15 in predetermined relation to the thickness of the wall of sugar as it is revolved by the shaft 12.

To this end the periphery of the cam 29 is positioned at various points different radial distances from the axis of the cam shaft 34, one end of the cam being provided with a flat face a at one end diametrically opposite to a point b that is shown as located from the axis of the shaft S4 twice as far as the nearest approach of said flat face to said aXis. rFhe limbs c and d of the peripheral face of said cam between the flat face a and the point Z) are alike.

The cam shown in the drawings is constructed to allow the roller 28 and consequently the nozzle l5 to hesltate or travel The 'stantially above the basket, and by maki slower when the stream is directed to the bottoni of the` sugar column 14 than during the other periods of its travel, the change from down to up motion being made with slower travel of the nozzle; as the spray is directed toward the upper portion of the sugar column the speed is accelerated; and the downward motion of the nozzle is retarded as the spray approaches the base of the column.

The worm gear 32 is fixed by pin 65 to a shaft 34 which is -iournalled in a cylindrical oscillating bearing 36 and has a shoulder 37 that abuts the shoulder 36 of bearing 36 so that when the gear 32 is secured in place the shaft 34 is locked against endwise movenient.

The end of bearing 36 opposite to the worm gear 32 is provided with a lug 39 that is pivotally mounted on the extension 40 on the end of the box 26; and through the lug 69 and extension 40 there is a pin 4l that permits pivotal movement of the bearing 36-and associated parts.

Bearing 66 is open ononeside so that th teeth 42 of the worin 43 on the oscillatable shaft k34 can engage theteeth 44 of the timing worm gear 45 when the sleeve 36 is moved to bring the worm gear 32 into mesh with the teeth of the worin 46; for normally the gear 32 is disengaged frointhe worm 46.

The drive shaft 47 to which the worm 46 is ecured extends upward from t-he top of the box 26 and has on the upper end thereof the pulley 48-that is connected by a belt 49 to thecentrifugal shaft l2 and. by this connection the worin 46 is enabled to drive the shaft carrying the actuating members when the latter require driving.

To those acquainted with the art the importance will at once be apparent of establishing this belt connection at a point on the centrifugal shaft substantially above the basket and stationary curbing 3, l ofA the centrifugal, Abecause the lateral rj'rations of the shaft and basket are often large especially toward the bottoni of the shaft where the basket is fastened. and these gyrations are smaller or negligible at points subthis'belt connection at approximately he level shown vin Figure l, the difficulties arising from gyration, and from other operative conditions, are practically eliminated.

However, the precise point onthe cen-Vv trifugal spindle at which this driving connection is made can of course be varied considerably with more or less advantage according to the opinion of the builder or user of these machines, and this driving connection with the centrifugal spindle can be made either directly on to member l2 or on to any member connected and rotating with member l2. Also though l have shown the belt and drive shaft 47 as a preferred form of driving connection between the centrifugal spindle and the washer mechanism, yet this .form can be considerably varied, and the belt can be replaced by any other well known driving expedient such as a chain, orv the like, without departing from the spirit of my invention.

The worm gear 32 is moved into mesh with the driving worin 46 by the following means; a rod 50 has its lower end mounted in the socket 5l of the upwardly extending bearing 52 that is integral with the bottom of the box 26. I

The rod 50 extends upward through the top of the box 26 and has on the upperend thereof the hand lever l53, by which the rod 50 is turned.

Within the box 26 there is securedto the rod 5G the hub 54 which hub has thereon the dogs 55 and 56.

When the 'lever 53 is moved vfrom the full line toward the dotted-position shown in Fig.` 4 it turns the rod 50,' and this movement of the rod' 50 causes the dog 56 to engage the dog 57 on the extension-58 of bearing 36, and this causes the rounded portion 59 ofthe dog 55 to engage the rounded portion 60 of ythe latch 61. K

As the lever 53 is movedon to the dotted positionabove referred to the dog 55 will push the latch 61'out of the way or until the edge 62 of the dog 55 has passed the edgev 63 of the latch 6l after which the spring 64 against which the latch has been pressed vwill force thelatch outward and lock the rod 50 against an opposite movei ment.

In the meantime the dog` 56 will push ythe dog 57' in the'direction of thel arrow shown in Fig. 7 and this movement of parts will move the sleeve 36 on the pivot pin 4l and bring the worm gear 32 into mesh with the teetli of the worm 46 and also bring the worm 43 into mesh with the worin wheel 45. f v Also the movement of the lever from the full line to the dotted position inFig. 4 accomplishes another movement of parts that are connected to the rod 50. There is secured to the rod 50 by the pin 65 a hub 66 that has extending therefrom the arm 67 to the outer end of which is xed the Vsegmental lsleeve pulley 68 to one end of which segment is secured one end of the spring 69 having its other end secured to a bolt 70 that extends through the end of the box 26.

About mid-way of the arm 67 there is pivotally secured by the pin 71,1one end of the connect-ing bar 72 the other end of which is pivotally connected by the pin 73 to theV outer end of the vlever 74, the inner end of which is fitted at `75 to the cock stein 76 of a common water pipe cock 77.

When the lever 53 is moved to the right mesh. a tension on trie spring 69 is established and the pipe cock 77 is opened so that water under pressure from a supply not shown will pass through the pipe 78.y cock 77 and flexible pipe 79 to the pipe 20 to discharge from the nozzle 15.`

As soon as the teeth ot the worm gear 32 mesh with the teeth ot the rotating worm 46. the shaft 34 will be rotated to actuate the cam 29 to rock the rocker arm 27, and oscillates shaft 24, thus oscillating pipe 20 and causing the spray of water from the nozzle 15 to sweep alternately Jfrom top to bottom of the centrifugal basket 8; so that the spray will be applied to the entire inner surface ot the sugar wall 14.

It isvnecessary to proportion the washing water to the thickness ot the sugar wall;

and it is necessary in determining theamount of washing water required, to consider the adhesiveness ot the molasses remaining in the sugar; and this variation in thickness of the sugar wall and adhesiveness of the molasses necessitates a wide range in the application or water. some sugar walls requiring` very little and some a very large amount to cleanse them.

From the foregoing it can readily be seen that it is necessary to have a quick and Yeasy means for varying the amount orP washing water applied to the sugar wall; and in this invention this variation is controlled by a timer that is connected to the apparatus, and is operated by the timing worm 43 which worm is moved into mesh with the worm gear 45 by operation of lever 53.

The worm gear 45 is loosely mounted on the bearing pin 80; and the pin 80 has a reduced end 81 that is mounted in the bearing block 82 which block is integral with the box v26, also the upper end of the bearing pin 80 passes through an opening y83 in the lid ot the box 26; and on the extending end ot the bearing pin 80 there is secured by the pin 84 the shank of the timing lever 85,A see Fig. 12.

lVithin thebox 26 there is secured to the timing pin 80 by a pin 86 the hub 87 of a movable stop 88; and the purpose ot which is to limit the movement ot the worm gear 45.

The worm gear 45 has integral therewith the hub of the sleeve pulley 89 and. to this pulley is attached one end ot a spring 90 which spring has its other end secured to the wall of the box 26 by the screw 91; and normally this spring is under tension and holds one end of a pin 92 in engagement with the stop 88.

The pin 92 isof considerable length and is shrunk or tightly secured in the hub of the worm gear 45 and integral sleeve pulley7 89 and the ends of this pin 92 extend beyond the pulley and gear. The upper end of the pin 92 contacts with the stop 88 and limits the movement of the worm gear in the direction ot the spring tension; andthe other end of the pin 92 contacts with the pin 93 on the latch 61, and moves the latch against the spring 64 when the worm gear 45 is actuated by the worm 43; and as seen. in Fig. 9 the pin 93 is guided by the side walls of the slot 92' and this slot is in the casing 61 in which a latch 61 is mounted.

When the lever 53 is swung from the spraying position ot Fig. 6 to the rest po-v sition or Fig. 7 thus oscillating rod 50, dogs 55, 56 and bearing 36, to mesh worm gear 32 with worm 46 and worm 43 with worm gear 45, the gears will be locked in mesh by the latch 61 engaging and holding the dog 55; and the gears will be driven by shaft 47 thus rotating worm gear 45 until pin 92 engages pin 93 on latch 61 and moves said latch to release the dog 55; and thereupon the spring 69actuates the arm 67 which Vturns the rod 50 and associated parts back tothe spraying position shown in Fig. 6.v This movement of the'rod 50 causes the cam surface 94 of the dog 56 to act on the'surtace 95 of the oscillating` bearing 36 to move said bearing and associated parts back to their rest position, thus releasing worm gear 32 from worm 46 and worm gear 45 from worm 43.

Then the worm gear 45 .is released trom the worm 43 the spring 90 moves the gear back until the pin 92 contacts with the stop 88.

Also as the spring 69-moves the arm 67, the bar 72 will move the lever 74`and close theV cock 77, which of courseshuts off the supplyV oit water to the nozzle 15.

From the foregoing it can readily be seen that after a number ot revolutions ot the worm 43 the worm gear 45 will be turned to release the latch 61 and permit the worm gears to be disengaged and parts to returnrto normal or idle position.

A means is providedL for kincreasing or decreasing'the number of revolutions of the worm 43 to release the latch 61, thereby inv creasing or decreasing the amount ot water passing to the spray nozzle 15. k

Integral with the outer end of' the leverv 85 is an upwardly extending cylindrical boss` 96 in which there is mounted the pin 97.

The pin 97 has one endthereof passing through the reduced opening 98 in the upper end ot the boss 96 and on this end of the pin 97 is secured by a pin 99 the knob 100.

Near the lower end ot the pin 97 and integral therewith is an enlarged portion 101, the upper surface ot which forms a seat for the spring 102; and the other end of the spring 102 contacts with the shoulder 103 at the upper end of the cylinder in 'the' boss 96. y i

The portion of the pin 97 below the enlargement 101 is adapted to t into any one of a plurality of holes 104 in the raised portion 26 of the box cover 26 and these holes are an equal radial distance from the center of the pin 80 so that when the pin 97 is lifted to free the lower point thereof from one of the holes 104 the lever 85 can be moved to another position where the pin 97 will register with another of said holes; and by releasing the knob 100 the spring 102 will force the pin 97 downward to lock the lever against further` movement.

The purpose 'of the lever 85 and its associated parts is to move the stop 88 either toward or away from the pin 92 and as previously stated this movement of the stop 38 either increases or decreases the number of revolutions of the worm 43 before the trip disconnects the worm gear 32 from the drive worm 46.

In other words when the lever 85 is in a position where it contacts with the stop 105 the worm 43 will need to turn but five revolutions before it has moved the worm gear 45 to a position where the pin 92 will release the latch 61 and disconnect the driving mechanism; and when the lever 85 contacts with the stop 106 the worm 43 will make about fifteen revolutions before the trip is tripped, consequently to increase the applications of washing water to the sugar lever 35 is moved toward the stop 106 and to decrease tlie wash the reverse movement of the lever is made.

Also it'will be understood that at each revolution of the shaft 34 the cam 29 and spring 30 will operate the lever 27 to move the shaft 24 and consequently rock the pipe 20 down and up which moves the spray nozzle 15 and applies to the wall of sugar a spray of water; and, as previously indicated, the wall of sugar is rapidly rotated by the centrifugal so that in reality the downward movement of the spray defines on the sugar wall a helixv that is reversed as the spray moves upward.

In operation the operator determines from the thickness of the sugar wall and adhesiveness of thev molasses remaining after the sugar wall has been formed in the basket, how much water will be required to wash the sugar and accordingly moves the lever 85 to a position that will give the desired result. Then the lever 53 is moved from the full line to the dotted position shown in Fig. 4, which will move the worm gear 32 into engagement with the worm 46 on drive shaft 47.

Also this movement of the lever 53 will operate the latch 61 to lock the worms and worm gears in engagement until the latch 61 is released as heretofore described; and in the meantime of course the cock 77 has been opened and the spray nozzle oscillated to wash the sugar; and when the latch 61 is released the cock 7T is automatically closed.

portant than might at first appear.

12, the belt 49, the vertical shaft 47 and the worm 46, constitutes only a train of driving mechanism, as will be apparent from the fact that the ksole and exclusive function of this entire train is to drive or to transmit` power into the important subsequent mem` bers Where the true actuating or functional movements of the washer are performed.

The first of these actuating, or truly functional, members, beyond the train of driving mechanism, is termed the actuating shaft, and comprises the shaft 34, carrying the nozzle actuating cam 29, and the timing worm 43, the actuating functions of these members being obviously the two most important functions in the entire device.

This invention is characterized by the fact that this actuating shaft is allowed normally to lie idle and at rest, and that it operates only for very brief periods, perhaps fifteen seconds every four minutes about, while the actual work of spraying the sugar is in process. This prolonged idleness is more im- In manufacturing these washers this actuating shaft and parts are originally made and fitted with a high degree of accuracy in or der to insure the accurate and scientific distribution of the wash-water contemplated in this class of washers. Consequently since continuous operation of the actuating shaft, produces unnecessary wear in the bearin s, and thus impairs the accuracy of the was ing function, this normal idleness of the actuating shaft eliminates all unnecessary wear and protects this member, thus prolonging the original accuracy and usefulness and reflecting creditablv on the value of the entire machine.

Gn the other hand, though the driving worm 46, and the other parts in the driving train above mentioned, operate somewhat more than the actuating shaft, this is of little consequence, as the driving members are relatively cruder than the actuating members and the wearoccasioned in the driving members by slight excess operation, in no way impairs the accuracy with which the real washing function is performed. However, it should be noted that even this driving worm, and other driving parts, do not operate constantly, but only interinittently with the centrifugal, there being, during normal operation, substantial opportunities of rest occurring periodically about every four minutes when the centrifugal iS the wear and tear on these parts is also reduced, and this reflects further credit upon ythe life of the machine and its usefulness.

However, it should be understood that by driving direct olf the centrifugal shaft, particularly from a point on the centrifugal shaft substantially above the centrifugal curbing as illustrated, I secure not only the advantage of reducing the wear as explained, but also the important advantage of eliminating all electrical troubles incident to the use of individual motors which were the usual power source in centrifugal washers before my invention was brought tov the attention of the public.

In conclusion it will therefore be seen that in addition to the basic advance in driving directly from the centrifugal shaft, my invention is largely directed to the important object of prolonging as far as possible, the original high degree of accuracy with which these washers are made, this being particularly important in the class of scientific washers of which I have illustrated an example, and I attain the desirable object justmentioned principally by eliminating unnecessary wear through allowing the main actuating members and actuating shaft to lie normally idle, calling this shaft into operation only for the very brief period actually required to distribute the wash-water while same is flowing, and thereafter allowing it to go back to rest until the next washing period arrives.

In the foregoing partsof this specification I have now described minutely the preferred form of my invention, but I wish to point out that it is only the preferred form and is subject to extensive remodeling and changing without departing from the spirit of my invention, and especially I do not limit myself to the particular type of driving train shown between the centrifugal shaft and the actuating shaft, nor do I limit myself to the precise details of the actuating shaft as the same may carry only one of the actuating members in place of both, and the actuating members may be formed to embrace the shaft integrally therewith in place of having a separate piece of shafting therein, and in general I do not limit myself in any particular except as such limitations are expressly set forth in the appended claims.
